HD74LV157A
Quad. 2-to-1 line Data Selectors / Multiplexers (Noninverted Outputs)
ADE-205-263 (Z) 1st Edition March 1999 Description
The HD74LV157A has four 2-input digital multiplexers with common select and strobe inputs. When the strobe input is low, a 4-bit word is selected from one of two sources and is routed to the four outputs. The device provides true data. Low-voltage and high-speed operation is suitable for the battery-powered products (e.g., notebook computers), and the low-power consumption extends the battery life.
Features
* * * * * * VCC = 2.0 V to 5.5 V operation All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VO (Max.) = 5.5 V (@VCC = 0 V) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25C) Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25C) Output current 6 mA (@VCC = 3.0 V to 3.6 V), 12 mA (@VCC = 4.5 V to 5.5 V)

Notes: The absolute maximum ratings are values which must not individually be exceeded, and furthermore, no two of which may be realized at the same time. 1. The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. This value is limited to 5.5 V maximum. 3. The maximum package power dissipation was calculated using a junction temperature of 150C.
